NEW JERSEY, ASSIGNORS TO THE WESTERN UNION TELEGRAPH COMPANY, OF

NEW YORK, Y., A CORPORATION OF NEW YORK COUPON FEED MECHANISM FOR TEIQEGEAPH PRINTERS Application filed July 27,

This invention relates to] printing tele-' graph machines of the type in which the selection of the printingcharacter is determined by a combination or electrical impulses, and

more particularly to a paper feed mechanism for a printer of this nature, and to the control of said paper feed mechanism.

In printing telegraph systems employln'gmachines of thisnature, it is usual to employ, at the transmitting station, a key-board transmitter, which, when a definite character key is depressed sends out a combination of electrical impulses, usually of five or six units, which are transmitted to the receiving station where the selecting mechanism of a printing unit, selects the particular type-bar on which the desired printing character is mounted. The selected type-bar is then moved against the tape or sheet of paper to form an impression, and the tape or pa e fed forward one letter space. The keyoard transmitter and printing unit at each station are usually combined into a single machine operated by a common motor, but may constitute separate units.

' The present inventionQis' especially conccrned with .the printing unit, but the mechanism embodying the invention is under the control of the operator, at the transmitting station, through the key-board transmitter. A type of key-board transmitter which may be employed in connection with this invention is disclosed in the patent to 'Krum,

1,595,472 granted 'August 10, 1926, and en titled Telegraph apparatus.

Telegraph printing machines, asheretofore constructed, are adapted only for continuous writing, that is, for eachsignal combination transmitted, the paper is fed forward a single letter space only. It is desirable, however, in certain kinds of business, such as brokerage houses, mail order concerns, department stores, banks, hotels and the like to transmit from one distant point to another, individual orders or messages consisting only of a few characters, and-in order to facilitate the handling and filing of such orders it is desirablethat they be received on individual slips or coupons of uniform size, somewhat larger thanthat required for the order or 1929'. swarm. 381,567.

message .alone. For instance, in the case of brokeragehouses, the orders should be of the same size and style as those written out upon the regular order blanks and delivered to the brokerage house by messenger, mechanical conveyor or by any of the forms of delivery 1n common use. The inventionis particularly adaptable to the brokerage business in which ialarge proportion of the telegraphic trafiic consists of buy and sell orders of only a few characters in length. A Y One of the objects of the present invention. is to provide an apparatus for use in conjunction With a telegraph printing unit which will enable the operator at the transmitting station to transmit the order or message to the receiving printer and at the completion of the order to automatically. space out the proper length of tape or sheet to form an individual slip or coupon of uniform length in each instance. I

A further object is to provide a printing telegraph machine for producing, in response to transmitted signals,'a messa e sli of uniform size independent of the engt of the message, and for detaching or indicating the place of detachment of the slips or coupons rom the roll or paper web.

Another object is to provide means for enabling the-length of the slip or coupon to be varied.

Other objects and advantages will appear as the description proceeds.

It is possible, of course, with the prior forms of tape printing telegraph machines to produce a coupon of any desired length by actually counting the number of message characters transmitted in each instance and then spacing out the tape to the desired length by successively operating arspace or non-intelligence character key lever at the key-board transmitter, but this is impractical since the number ofmessage characters diiiers in each instance, and the procedure is tedious and susceptible to. errors on the part of the operator.

In accordance with our invention We providethe printing uniti-n addition to the main step by step paper-feeding mechanism controlled by the transmitted message, with an auxiliary paper feed mechanism which is set into operation after the message'has been completed, by the actuation of a definitekey lever of the keyboard transmitter, to feed the paper automatically an additional distance, such that the coupons will be of the same length in each case irrespective of the length of the message. In the embodiments of the invention disclosed herein, the actuation of the auxiliary tape feed key lever of the key-board transmitter causes a predetermined signal combination to be transmitted to the printing unit which, through the regular typebar selecting mechanism of the printer, causes an electrical contact to be closed, thus completing 'a circuit through a magnet which operates a clutch mechanism for connecting the shaft of mechanism to a v the correct length of paper has been advanced page printing through the machine, irrespective of the length of the message.

At the termination of the paper feeding operation, the coupon may be severed from the paper web, perforated, scored or otherwise marked to indicate the proper length of the coupon.

The typebars are selected in the usual manner by a group of semi-circular notched code bars 13 controlled by selecting cams (not'shown) in response to the received combination ofelectrical impulses, to bring a single set of notches in the code bars into alignment, whereby the pull bar 14, corresponding to the selected character, will be pulled into the aligned notches and thus brought into'a position to be engaged by the operating bail 15 on upward movement thereof.

signal.

This is well known inthe ,art and forms no part of the present invention, except in so far as it operates in conjunction with our auxiliary paper feed mechanism, and controls thev operation thereof through the received signal combination. Therefore, it will not be necessary to describe the samein further detailfor a proper understanding'of the present invention.

The parts of the pr subject 'matter of our invention are shown in heavy lines in Fi ure 1. ,A platen 16 is provided with space paper supporting rollers 17 and 18 to permit the use of a relatively wide tape 19, shown in dotted lines in Figure 1. The tape passes from right to left over the platen and under the spaced pressure roll"- ers 20 and 21', mounted upon a shaft 22 driven i ting unit forming the I form of printing telegraph machine the platen through gears 23 and 24.

b 'l hese pressure rollers are mo nted on a Q18.I1k arm 25, shown in Figure 4, and are pressed against the platen by a spring, not shown, to hold the tape therea inst so that it will be moved forward durm disp psed immediately above the platen roller-l the rotation of the platen; Aninking ribbon 26 is which is provided on its inner end with a driving gear 28 mating with a gear 29 secured to the end of a main paper feed shaft .30 disposed parallel to .the platen shaft. The drivmg gear 28-is of substantially double the mounted upon a vertical plunger 31 (see Figure 2) having a cam face 32 which engages the horizontal arm 33 of a bell crank lever pivoted 'at' 34. Upon upward movement of the plunger the horizontal arm 33 of the bell crank lever moves into the depresslon formed by the cam surface of the plunger and through the vertical arm of'the bell crank lever moves the ratchet pawl 35 downward. The ratchet pawl is arranged so as to engage one of the teeth of the spacing ratchet 36 upon the downward movement thereof so as to rotate the ratchet through one space upon the subsequent upward movement thereof. The upward movement of the pawl occurs when the operating plunger is returned to its normal lower position. Rotation of the ratchet 35 advances the paper through the machine through the rotation-of the platen.

In addition to this '-regular paper feed mechanism, we have provided an auxiliary paper feed mechanism which is. set into operation after the completion of the message by the depression of a special tape feed key lever of the key-board transmitter. This auxiliary paper feed mechanism continues the feeding of the paper until the predetermined length has been advanced through the machine.

A gear 37 is mounted upon an extended part of the main paper feedshaft 30, opposite the spacingratchet 36.{ The gear 37 meshes with a bevel gear 38 mounted on the end of the auxiliary paperfeed shaft 39 which is disposed at right angles to the shaft 30.

. A driven member 40 of a c1utch'41 is disposed at the opposite end of the shaft 39 from the gear 38. The driving member 42 c of the clutch is secured to a shaft'43 driven by a motor 44 by worm-wheels 45 and 46, vertical shaft 47, worm-wheels48 and 49, horizontal shaft 50 and bevel gears 51 and 52. The motor 44 preferably, also constitutes the source of power employed tov operate the printingmechanism, but if desired separate operating motors may be used.

The clutch 41 may beof any convenient type and as shown consists of the two crown gears 40 and 42,, the gear 42 being rigidly fixed upon its shaft 43, and the gear 40 being slideable longitudinall on its shaft but conneetedby a key and s ot connection 53 to a fixed element 54 secured to the shaft 39 so' as to rotate therewith. The driven element 40 of the clutch may be moved into engagement with thecontinuously operating driving member 42 to transmit motion to the shaft 39; The operation of this clutch is controlled'by a magnet 55, the armature 56 of.which has a yoke 57 attached thereto. The legs of the yoke engage in an annular recess 58 of the driven clutch member 40 and move the two clutch members into engage ment and disengagement upon energizing. or

deenergizing the magnet. A spring 59 disengages the clutch upon deenergization of the magnet.

With-the foregoing mechanism it will be noted that the paper may be fed forward either by the normal feed mechanism including the pawl and ratchet 35 and 36 or by the auxiliary paper feed mechanism, controlled by the clutch 41.

The energizing of the magnet 55 for initiating the operation of the auxiliary paper feed is controlled through the keyboard transmitter. At the conclusion of the transmission of the order or other message, during which a definite quantity of tape has been fed. if it is desired to cause enough blank tape to be automatically and additionally fed out so as to give a uniform length of slip or coupon,

the transmitting operator depresses the special tape feed key to transmit a signal combination which will operate one of the pull bars 14 which is so disposed as to engage 2; pair of normally open cont-acts 60 and 61 to close the same and thus complete a circuit through the magnet 55 and a locking relay 62, from the ground 63 by way of conductors 64,65 and Y66. 'The relay 62 through its armature 67 completes 'a locking circuit through the winding of the magnet 55 and the relay 62 from the ground 68 by Way of the armature 67, conductor 69,contacts 70 and 71 conductor 72, relay 6 2, conductor-65,

magnet 55 and conductor 66. I

The contacts 70 and 71 form part of a timing device,.the purpose of which is to .discontinue the operation of the auxiliary paper feed mechanism after the desired length of tape has been fed to form the coupon. The contacts 70 and 71 are'controlled by a cam 74 mounted upon the shaft 39. The cam 74 has a recess 75 in one side thereof which at the beginning of the operation of printing a coupon is opposite the contact 70, so as to enable the contacts to. be open. Upon the printing-of the first character of the order or message, the normal tape feeding mechanism is operated through the pawl and ratchet 35a nd 36to advancethe tape and atthe same time to rotate the cam 74-;through the gears 37 and 38. The rotating of the cam 74 in response to the firstprinting signal causes the contacts 70 and 7]. to close.

The cam is moved around with each subse-- quent printing signal.

After the message has been completed and it is desired to space out the tape to form the definite size coupon, theauxiliary tape feed -mechanism is set into operation by actuation of the tape feed key lever and the subsequent energization of the clutch magnet 55 and the locking circuit, including the contacts 70 and 71. The auxiliary tape 'feed mechanism continues to operate until the cam 7 4 makes a complete revolution and the recess 75'again comes into position opposite the contact 70, at which time the contacts open and thus break the circuit through the clutch lmagnet 55 and the locking relay. 62. The retractile spring 59 causes the disengagement of the clutch 41.

' The length of the coupon is definitely determined by the cam 7 4, which being actuated by both the normal printing operation and the auxiliary a or feed mechanism causes the feedin o t e aper to be uniform revided so that a single revolution of the cam gardless o? the nuin er of characters in the messa e.

While we have shown the cam 74 as pro- I vided with a single recess, it is tobe'understood that, any number of recesses may be prowill control the feedin of several slips or coupons; Thelength of the coupons may be varied by changing the spacing of the 'recesses in the cam and/or by changing the mounted upon the shaft 39. A set of normal-.

ratio of the gears 37 and 38.

It may be desired to automatically cut-ofi the printed slip or coupon after the predetermined length thereof has beenfed out. This is accomplished by passing the tape, as it leaves the printing platen, betweenthe jaws 76 and 77 of a paper severing device.

The jaw 77 is fixed and the jaw 76 is ivoted to a fixed support 78 and is norm yheld open by a spring 79.

The operation of the jaw '7 6 is effected bya solenoid 80 controlled by a second cam 81 ].y open contacts-82 and 83 are disposed ad-v jacent the cam 81 so as to be periodically closed thereby to complete a circuit through the solenoid 80 from the ground 84by way of conductors 85, 86 and 87 to a source of current. The cam 81.has a projection 88 which is disposed in such relation to the recess of the cam 74 that the contacts 82 and 83 are closed at the termination of the paper feeding operation to operate the. tape severing means. I y In case 1t1s desired to separate the slips at some later time or to have the tape marked so as to facilitate the subsequent separation of the couplons, a set of pins mounted ina row upon t e jaw 76 may be substituted for the-shearing jaw to perforate the tape. Obviously other means controlled by the solenoid maybe employed to indicate the correct length of the Coupon. 4

7 Referring to Figures 3 and 4., we have shown an alternative method of stopping the auxiliary tape feeding mechanism which may be used in place of the timing cam 74.

The roll of tape is perforated at uniform distances alon one edge',-as indicated at 89 before being p aced in the printer; the spacing of the perforations being equal to the desired length-of the coupons. The tape passes between two electrical conta'cts 90 and 91 normally held but of contact by the tape but .92 by way of the armature 67 of the locking relay, conductors 93, relay 62, conductor 94, magnet 55 and conductor-95 to the source of current. I

The operation ofthe auxiliary paper feed is continued until one of the perforations 89 of the tape is moved opposite the contacts 90 and 91 to permitthesame to close. This short-circuits the winding of the locking re- .lay 62 so thatthe armature thereof is Withdrawn by a spring 96 thus opening the circuit to the clutch ma 'netand discontinuing the paper feed operation. The cam 81 which controls the severing device may be provided on the shaft 39 and adjusted so that it operates the paper severing blades at the completion of'each coupon feeding operation.

- In Figures 7 'to 10 inclusive, we have illustrated -our invention applied to. a page printing machine as distinguished from the tape. printing machine described above. In

Figure 7 we have shown a page printing machine having a casing 97 within which the type bars 98 and the type bar selecting and operating mechanism is disposed. The type bar. selecting and operating mechanism is shown diagrammatically in Figure 8 and it comprises the usual horizontal code bars 99 shiftable longitudinally in accordance with thereceivin signal combination to align a single set 0 notches in the bars to permit a definite push-bar 100 to move into ,the

aligned slots. The push bars,on,e of which is provided for each type bar, are normally held 'away from the code bars by a depressing bail 101, against the act-ion of a spring lOQ. The

depressing bail is mounted on a crank 103' pivoted at 104 and connected by an adjustable link- 105 to one arm 106 of a two armed lever 107.- The second arm 108 of the-lever has a roller 109 engaging "with a cam 110* which normally holds the pawl 101 depressed. As soon as the code bars have been shifted in accordance with the received signal com-. bination, the cam 110 revolves sufficiently to release theroller 109 and permit the depressing bail to be raised.

Spring 102 then-moves the selected bar into the aligned slots so as to elevate the notch 111 in front of a striker bail 112 secured to a crank 113, which is actuated by a second cam 114, crank 115 and link 116 to movethe pushbar forward. The forward movement of the push bar throws the type bar 98. upward"? against the platen by means of'the lever 117 and link 118. I

This form of-type bar selecting mechanism is well known in the art, and further description thereof is believed to be unnecessary.

The type bars move upwardly against a cylindrical platen 119 carried by a longitudinalshiftable carriage. The platen is niounted upon a square shaft 120 so as to rotate therewithito effect the line spacing operation but 'shiftable longitudinally thereof to effect the letter spacing operation. -'The line spacingis accomplished during the normal operation of the printer by a feed pawl .engaging with a ratchet (not shown) fixed to the square shaft 120.

. 127 and 128. Theclutch 41 is controlled by In the application of our invention to a page printer of this type, to automatically space out a definite length of paper after the termination ofthe message, wefconnect the square shaft 120 directly to a vertical shaft 121 by bevel gears 122 and 123 so that the normal linespacing operation will rotate the shaft 121. and with it the timing cam 81 secured to the shaft 121. The shaft 121 is connected to a continuously operating driving.

operation.

Upon complet1on of the message, the transmitting operator, if he desires to space out a uniform length of paper, d presses the auxiliary paper feed keyto ansmit' a predetermined signal combination for selecting a push bar which controls the actuation of the auxiliary paper feed mechanism. For this purpose, onejof the push bars engages at its freeend with-a contact arm 131 to normally maintain a pair of contacts 132 and 133 open. When the auxiliary paper feed signal is received, this push bar is actuated and upon forward movement permitsthe contacts 132 and 133 'to ,.close,' thereby energizing the. clutch magnet 55 and the locking relay 62 to set the auxiliary paper feed mechanism into 1 The circuit for the clutch magnet and locking'relay may be tra'cedfrom the ground 134 through conductor 135, contacts 132 and 133, conductor 136, locking relay 62, conductor nism, a paper engagin 137, clutch magnet 55 and conductor 138 to a source of potential.

.The locking circuit for the clutch magnet is completed through armature 67 of the looking relay and the contacts 7 0 and 71, of the timing mechanism, as previously described,

so as to terminate the operation of the auxiliary paper feed mechanism when the proper length of paper has been the machine.

In Figure 10 we have shown'a timing cam 81 ,provided with an adjustable means for varyingthe length of the paper.

A small plate 139, having an arcuate sur face 140 of the same radius of curvatures'a's the surface of the cam, is secured to the cam by a screw 141 in such position as to cover one 'of the recesses 7 Sand thus to maintain contacts 70 and 71 closed as the contact 70 passes over this portion of the cam. With the plate 139 in position, the length of the-slip or sheet will be determined by a single revolution of the-cam.

If it isjdesired'to produce a coupon of half the length, theplate 139 may be shifted away from the recess, to the dotted line position, to uncover the recess and thus cause the contacts 70 and71 to open at each half revolution of the camp It is to be mam-stead that the invention is not limited to the specific form of printing unit disclosed here n, but is applicable to other types,'and since the invention is sus nism afterla predetermine length of paper has been advanced through the machine,
